ATo all whom it may concern:

Be it known that I, DANA H. BENJAMIN, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio,have' invented certain new,

and useful Improvements in Gearing for Washing-Machines, of whichthefollowing is a specification..

This invention relates generally to methem successively .into and out ofengage-v ment with the receptacle -driven member.

The invention may be further brieily summarized as consisting in theconstruction and combination of parts hereinafter set forth in thefollowing description, drawings and claims.

Referring to the drawings, Figure 1 is a side elevatlon of the deviceapplied with parts broken away; Fig.4 1a is a detail sec-l -tion of thewedge adjustment for the cam.;

Fig. 2 is an end view with one gear case in sect1on;.F1g. 3 1s asectional view taken on the line corresponding to a vertical planecutting the axis of the driven member and back of the oppositely drivenfriction wheels; Fig. 4 is a horizontal section taken on a line cuttingthe axis of the driven member; and Fig. 5 isa vertical sectional view ofthe driving mechanism; Fig. 6 is ato plan view of the trough andcylinder; an Fig. 7 is a cross section of these parts.

' In carrying out the invention any preferred form and construction ofparts may be employed so long as it possesses the neces-- sarycharacteristics, but I have shown one arrangement which is effective,and in s uch embodiment 1 represents asuitable framework provided with atrough-shaped rece -Y tacle 2 having suitable heads 3 and 4, t e formerbeing provided with a bearing consisting of a fianged sleeve 5 extendingthrough the head and having threaded to the inner end a flange 6 adaptedto be ses cured to the inner face of the head. The

opposite head 4 is provided with a bushing 7 adapted to receive a pin 8arranged in the bushing and having a reduced trunnion portion 9. Thispin 8 is held in place by a lock pin 10 passing through proJe'ctingportion of the sleeve 7 and through the pin 8.

. Mounted in the bearing sleeve 5 is an agitator driven shaft or member11 having on the outside of the head 3 a main driving member 12 providedat its periphery with a ange 13. This flange is provided internally withan annular V-shaped groove 14 for a purpose to be described.A Thisdriven member is also provided with a suitable pilot or shaft extension15, as shown in Fi 4. The inner end of the driven shaft 11 1s providedwith a squared portion 16 entering a correspondingly shaped opening inthe socket member 17 secured in the head 18 of i a cylindrical agitator19, the other head 20 of this agitator being provided with a suit- Aablebearmg-member 21 adapted to receive and adapted to e closed by a door orplate 24 having cleats 25 on the bottom thereof. These cleats haveextensions 26 extending under the wall at one ed e. About the oppositeed the outsi e wall'of the cylinder to hold the door in place at thispoint. The inner wall of the cylinder is also rovided withlongitudinally disposed ba e plates 27 spaced around the inner wall. Y

The mechanism for driving the driven l' shaft or member is mounted inacasing 28 having diametrically disposed-bearings 29 and 30 which receivea diagonally disposed a suitable latc 27 is provided on operating shaft31 which is further mounted 1n bearings 32 and 33 secured to the head 3.This shaft has on its lower end a gear 34 driven by a pinion 35 operatedby a motor. The upper end of the shaft is provided with a bevel pinion36 meshin wltha gear 37 secured to a verticallydisposed shaft 38, shownin dotted lines in Fig. 1, and having upon the upper end a bevel inion39, engaging a bevel gear 40 moun u on a shaft supported in a bearing 41and a on the opposite side of this bearinga, cutch member 42. Thisclutch member is adapted to be engaged by av wringer clutch member 43slidably mounted upon a wringer i 44. This shaft is provided with awringer 'mounted upon the shaft 49.

roll 45 engaging with another wringer roll 46, both of which aresupported in a suitable framework 47.

The driving mechanism will now be described. Forming part of the frontof 'the casing 28 is a bearing 48 having mounted therein a shaft 49extending into the casing 28 and to a point within the flange 13 of thedriven shaft or member 12. This shaft has loosely splined to it, justinside of the front of the case, a clutch member 51 having a groove adated to receive the ends of a forked shifting lever 52 pivoted to asuitable bracket 53 formin a part of the case. The handle 54 of thisever projects' up through a suitable opening in the casing. This clutchmember coperates with a clutch member 55 integral with'a worm gear 56loosely This worm gear meshes with a worm 57 secured to the shaft 31.Secured to the shaft 49, just inside of `the worm gear 56,- is a maindriving gear 58 for a purpose-to be described. The shaft 49 is continuedloosely through a swinging frame 59 vand through the end of a link 60which has a bearing portion 61 at its lower'end adapted tengage thepilot shaft portion 15 of the driven shaft' 0r member. In this way theshaft 49 is supportedfatA both ends with respect to the axis of thedriven shaft or member. The swinging orj pivoted frame 59 is providedwith a bearing 62 for a direct drive friction wheel shaft 63, a bearing64 for a reverse friction wheel vdrive shaft 65, and a back gear shaftsupporting boss 66 carrying a back gear shaft 67. This frame is alsoprovided with an outwardly extending bracket 68 shown in Fig. 1 andhaving on the outer end a pair of bearing boxes 69 which support a wormshaft 70 upon which is mounted a worm wheel 71 adapted to be driven bymechanism to be described. The outer end of the shaft 70 is providedwith a cam 72 adapted for engagement with a suitable stop preferablycomprising a wedge 73 mounted in a bracket 74 secured to the head 3.This wedge is held in any adjusted position by -beyond this same shaftis provided with a worm 78 meshing with the worm wheel 71. The shaft 65is provided with a spur gear 79 meshin with a back gear 80 mounted uponthe gear 80 in turn meshes with the main driving gear 58. 0n the insideof the swinging or pivoted frame 59 this shaft 65 is provided ack gearshaft 67. 'This back with a friction wheel S1 similar in all respects tothe friction wheel 76 except that it has the opposite direction ofrotation. 1n order to vcause the cam 72 to normally remain in engagementwith the wedge 73a spring 82 is arranged between an ear 83 4on thebracket 68 and a fixed bracket 84 secured to the main frame. In thiswaythe entire swinging frame has a tendency to swing in a clockwisedirection on its center, thus maintaining the engagement between the'cam and the wedge.'

In operation the door of the cylinder is `opened and the articles to bewashed are 1nserted and the door closed, suitable washing solutionhaving been previously placed in the trough or tub. The clutch member 51is thrown in the proper direction to cause the driving of the maindriving gear 58 with the result that the two friction wheels 76 and 81are driven, and in like manner the cam 72 is driven, causing,theswinging frame to bring one or the other of the friction wheels intoengagement with the driven shaft or member of the receptacle.

This causes the receptacle cylinder to bel 2. A mechanical movement,comprising adriven member, a movable supporting frame,
